Blower > Heat > Min distance???

Is there a min distance I need to keep between the outlet of the blower and the inlet of the heat element chamber? Also, will the perforated steel under my blower inlet restrict airflow too much? https://www.dropb...2.JPG?dl=0 https://www.dropb...3.JPG?dl=0

I can use a 2" one to connect to some steel pipe but want to make sure the EMT that feeds in/out of the ammo can: (1) Doesn't melt/explode (2) Won't poison me You know... the little things in life

1 1/2 Pounder Posts: 634 Joined: April 13, 2012	Agreed triclamp fittings would be the obvious and best option but I had these lying around and didn't know what the heat rating was or if they would melt give off toxins etc. I thought these were steel?
